UNIVERSAL HANG ER.

SPECIFICATION forming part Of Letters Patent N0. 548,808, dated OCtOber29, 1895.

Application iiled July 23, 1894. Serial No. 518,331. (No model.) l

To all whom t may concern:

Be it known that I, ERNST J. MULLER, of Butte, in the county of SilverBow and State of Montana,- have invented certain new and usefulImprovements in Universal Hangers; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings, andtothe letters of reference marked thereon, which form a part of thisspecification.

The main objects of my invention are to facilitate the alignment of anumber of boxes with each other without disturbing the brackets,hangers, or stands which support them, to prevent the boxes from bindingon the shaft which they support by permitting them to turn in anydirection transversely to their axes,and thereby adapt themselvesautomatically to any ordinary springing or deflection of the shaft froma straight line, and to provide for a slight adjustment of the shaft in4any direction transversely to its axis.

It consists, essentially, of certain novel features in the constructionand arrangement of the box supporting and adjusting connections, ashereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same partsin theseveral tigures.

Figures 1 to 6, inclusive, show one form of my universally-adj ustablebearing adapted to hangers, Fig. l being a side elevation and partialvertical section transverse to the axis of the box; Fig. 2, a frontelevation of the same; Fig. 3, a horizontalsection of the yoke on theline 3 3, Fig. 1; Fig. 4, a vertical section parallel with the axis ofthe box on the line 4 4, Fig. 1; Fig. 5, a horizontal section on theline 5 5, Fig. l; and Fig. 6, a vertical section on line 6 6, Fig. 1.Figs. 7 to 10, inclusive, show a modification of the bearing, alsoadapted to hangers, Fig. 7 being a vertical section crosswise of the boxand a partial side elevation; Fig. 8, a front elevation; Fig. 9, ahorizontal section on the line'9 9, Fig. 7; and Fig. 10, a verticalsection on the line l0 10, Fig. 7. Figs. 11 to 14, inclusive, show stillanother modification of the invention,

Fig. 1l beinga partial side elevation and vertical section crosswise ofthe box; Fig. 12, a front elevation; Fig. 13, a plan view of the lowerhalf of the box and the yoke supporting it; and Fig. 14, a horizontalsection on the line 14 14, Fig. 11.

v Referring to Figs. 1 to 6, inclusive, A designates a bracket or hangeradapted to be bolted in the usual manner to a ceiling or overheadsupport and formed in line with each other with split hubs ot a', whichare provided with clamping-bolts a2 a2. In one hub a is threaded ahollow screw or sleeveB, having a squared end b, and in the other hub ais fitted a plain sleeve C.V D is a yoke formed on opposite sides withhollow stems d d', fitted, respectively, into the hollow screw B andsleeve C. The stem ol is provided at its outer end with a washer cl2,secured thereto by a bolt cl3, whereby said stem is secured in thehollow screw B and prevented from moving endwise therein, said screwabutting at its inner end against a shoulder on said stem and at itsouter end against said washer. Sufficient play is allowed to permit thestem to turn freely in said screw. Said yoke is formed perpendicular tothe stemsdd,with a sleeve d4, in the lower end of which is threaded ahollow screw E, squared at its lower end c.

F designates the box, the lower half of which is formed or provided witha vertical stem f,

reduced at its lower end and fitted in the hol- Y low screw E, in whichit is secured bya washer e and bolt c2. The unreduced portion of saidstem f is fitted to bear and turn in the upper end of the sleeve d4. Forconvenience in manufacturing and assembling the parts of the hanger thestems d d are flattened on the sides, as shown in Figs. 3, 4, and 6, soas to admit of their bei ng passed sidewise upwardlybetween the ears ofhubs a a into the bores thereof. sleeve C are then passed over the endsof said' stems and inserted in said hubs and when properly adjusted aresecured in place -by the clamping-bolts a2. The sleeve d4 of yoke D issplit at its lower end and formed on opposite sides-with ears, which areconnected byV clamping-bolts d5 d5, as shown in Figs. 2 and 5, wherebythe screw E may be secured in place when adjusted, as desired.

The stems d and d being free to turn in The screw B andv IOO theirbearings in the bracket or hanger A, and the stem j", at right anglesthereto, being free to turn in the sleeve d4 of yoke D, it is obviousthat the box F has universal-joint connections with its support and isfree to turn in all directions about its center and to adapt itself toany springing or deiiection of the shaft which it supports from astraight line.

By loosening the nut or screw a2 in hub ct and turning the hollow screwB thus released, by means of its squared end h the box F may be readilyadjusted horizontally transversely to its axis, and in like manner byloosening` the nuts on bolts d5 in sleeve d4 and turning the hollowscrew E, thus released, said box may be adjusted vertically. Thealignment of a number of boxes with each other is thus readily effectedwithout disturbing the brackets, hangers, or other supports which carrythem.

The hollow screw or sleeve B, threaded in the bore of hub d, and thestem d of yoke D constitute an adjustable pivot connection between thehanger A and said yoke, and the hollow screw or sleeve E, threaded inthe bore of sleeve d4, and the stem f of box F constitute a similaradjustable pivot connection between said yoke and box.

Referring to Figs. 7 to lO, inclusive, showing a modification of thedevice, A designates a bracket or hanger adapted to be secured to aceiling or other overhead support in the usual manner by bolts andformed with hubs a a3 in line with each other. The hub a, is split andformed on opposite sides with ears, which are connected by aclamping-bolt a2, as shown in Figs. 8 and l0.

B is a hollow screw threaded in the hub a and formed with a squared endh, by means of which it may be turned therein.

D is a yoke formed on opposite sides with internally-threaded hubs d6d6, in which are secured pivot-pins G G in line with each other. Thepivot-pin G is formed with a head g, between which and the adjacent hubd6 the hollow screw B is held thereon, sufficient play being allowed topermit said pin to turn freely in said screw. The pin G is fitted in thehub a3, and squared at its outer end to receive a wrench for turning itinto and out of the hub d6. Said yoke is also formed in a lineperpendicular to the pins G G with hubs Z7 and d8. The box F is formedor provided on the lower half with a hollow internally-screw-threadedstem f', which is tted to turn in the hub C17.

H is an ad justin g-screw threaded in the hollow stem f and formed witha plain extension or shank h, which is iitted to turn in the hub d8, andheld therein by a head or shoulder h and a nut h2. It is provided with achecknut h3, which is forced against the lower end of the stem f tosecure the parts in place when they are properly adjusted.

To assemble the parts of this form of my improved hanger, the yoke D',with the box F, is placed between the hubs a a8 of the hanger, with thehubs d d6 in line therewith. The

pivot-screws G G are then passed from the outside through the hollowscrew B and the hub d3, respectively, and screwed into said hubs d6. Thehorizontal adjustment of the box is effected in the same manner asexplained in connection with the form shown in Figs. 1 to 6. Thevertical adjustment of the box is accomplished by loosening the checknuth3 and turning the screw H by means of its nut h2, which is pinnedthereon for this purpose.

Referring to Figs. ll to il, inclusive, show'- ing another modificationof my improved bearing, the hanger or bracket A2 is formed or providedwith internally-threaded hubs d4 in line with each other, and in thesehubs are threaded pivot-pins l I, which are provided with check-nutsz't' for securing them in place when they are adjusted as desired. Theyoke D2 is formed on opposite sides with hubs d, having sockets toreceive and afford bearings for the ends of the pivot-pins I I. It isalso formed with hubs d7and d8 in a line perpendicular to saidpivot-pins,like or similar to those shown in Fig. '7. The box F isformed or provided on the under half with a stem f2, the upper part ofwhich is fitted to turn in the hub d"l and the lower part of which isreduced and externally screw-threaded.

J is a sleeve fitted to turn in the hub d8 and made a little longer thansaid hub. The reduced portion of the stem f2 is made to pass looselythrough said sleeve and is secured therein by nuts f3 and f4, the nut f3being placed on said stem in an opening in said yoke and formed withholes in its edges to receive a spanner wrench or pin for turning it.

The box is adj usted horizontally by loosening the check-nuts t' i andturning the pivotpins I I in or out, as required, of the threaded hubsa4 a4. The vertical adjustment of the box is effected by turning thenuts f3 andf4 up or down on the threaded stem f2, as required. Whenadjusted as desired, it is secured in place by turning the check-nuts t't' against the hubs a4 and the nuts f3 and f4 against the ends of thesleeve J.
